  1. 1. Movement Estimation with SLAM through Multimodal Sensor Fusion

    Master-uppsats, Linköpings universitet/Medie- och Informationsteknik; Linköpings universitet/Tekniska fakulteten

    Författare :Jimmy Cedervall Lamin; [2024]
    Nyckelord :slam; discrete-slam; continuous-slam; synchronous; asynchronous; computer vision; BRISK; opencv; ceres; visual; inertial; sensor fusion; multimodal; Simultaneous Localization and Mapping; time offset; pose estimation; quaternions; movement estimation;

    Sammanfattning : In the field of robotics and self-navigation, Simultaneous Localization and Mapping (SLAM) is a technique crucial for estimating poses while concurrently creating a map of the environment. Robotics applications often rely on various sensors for pose estimation, including cameras, inertial measurement units (IMUs), and more. LÄS MER

  3. 2. Towards a feedback system for upper body bodyweight exercises using multiple inertial measurement units : A user-centred approach

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Panagiota Papadopoulou; [2023]
    Nyckelord :IMU sensors; bodyweight training; machine learning; real-time feedback; push-ups; tricep dips; plank;

    Sammanfattning : This thesis explores the feasibility of developing an affordable and easy-to-use feed- back system that leverages information from multiple inertial measurement units (IMUs) to identify mistakes during upper body bodyweight training and provide real-time feedback to the user. To develop the system, a human-centered approach was used, which involved conducting semi-structured interviews with movement ex- perts and a workshop with targeted end-users to understand their needs.

  4. 3. Wrist Angle Estimation Using Two Wearable Inertial Measurement Units

    Master-uppsats, KTH/Medicinteknik och hälsosystem

    Författare :Arvin Razavi; [2023]
    Nyckelord :IMU wrist angle estimation; Wrist absolute angle; IMU-based human motion capture; orientation filter; Complementary filter; Kalman filter; IMU handledsvinkeluppskattning; handleds absolutvinkel; IMU-baserad mänsklig rörelsefångst; orienteringsfilter; komplementfilter; Kalman-filter;

    Sammanfattning : Hand-intensive work is closely related to the prevalence of upper body and hand/wrist work-related musculoskeletal disorders (WMSDs) in office work, manufacturing, service industries, as well as the healthcare industry. Some risk factors include vibrations, forceful exertions, heavy manual handling, repetitive motions, and prolonged nonneutral wrist postures. LÄS MER

  5. 4. Assessment of a Wearable Motion Analysis System : Predicting ground reaction forces and joint angles with IMU:s and pressure insole sensors

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Norman Mårten; [2023]
    Nyckelord :Ground reaction force; kinematics; pressure insoles; IMUs;

    Sammanfattning : The analysis of human movement is important for diagnosis of as wellas planning and evaluating treatments of disorders or injuries affectingmovement. Optical motion capture combined with force plates provideaccurate measurements, but are confined to laboratory settings limiting theirpotential usefulness in clinical applications. LÄS MER

  7. 5. Validation of a new iPhone application for measurements of wrist velocity during actual work tasks

    Master-uppsats, KTH/Ergonomi

    Författare :Mohammed Abderhman Abaid; [2023]
    Nyckelord :Angular velocity; goniometer; inertial Measurement Unit IMU ; “ErgoHandMeter”; percentile; correlation iii; Vinkelhastighet; goniometer; IMU ; ErgoHandMeter ; percentil; korrelation;

    Sammanfattning : The breakthrough in mobile technology and the development of smartphones, supplied with sensing devices such as Inertial Measurement Units (IMUs), has made it possible to obtain accurate and reliable data on the angular velocity for different objects. The available technical sensors for wrist movements, such as electrogoniometers, are costly, time-consuming, and need a particular computer program to be analyzed. LÄS MER
